About twice a year I'll buy microwave popcorn, and hate it. I burn it, it smells bad, blah blah blah. For a while now I've been seeing 'make your own microwave popcorn at home' things. Really? I mean, really?
Well, yeah. It works.
Paper bag, 1/3 - 1/2 cup popcorn. Roll the bag over & stick it in the microwave. As with any microwave popcorn, stand and watch it. Mine took about about 1 1/2 minutes. I used 1/2 cup, but won't use as much next time. There were some unpopped kernels, and my bag opened at the bottom, but I will do it again for sure.
and guess what? No weird stuff. It's popcorn. THAT'S ALL. Add your own butter & salt.
